Hmm, I really should get the up to date files at work.. but I don't think the battery changed so these are probably still accurate:
Level 1:
750 hull, 120 shields, 3 armor
143 damage/shot and 11 second cooldown so 13 DPS
Level 2:
1000 hull, 140 shields, 4 armor
171 damage/shot and 9.9 second cooldown so 17 DPS (rounded)
Level 3:
1250 hull, 160 shields, 5 armor
200.2 damage/shot and 8.8 second cooldown so 23 DPS (rounded)
